To aZZ whom it may concern:

Be it known that I, WARREN HILL, of Towanda, in the county of Bradfordand State of Pennsylvania, have invented certain new and usefulImprovements in Paper-Folding Machines, of which the following is aspecification.

The object of my invention is to provide a new and improved machine forfolding newspapers ready for wrapping and mailing.

The invention consists in a paperfolding machine constructed with aflier, toothed rollersections for creasing and folding the paper, and aswinging rod also for creasing and fold ing the paper.

The invention also consists in the construction and combination of partsand details, as will be fully described and set forth hereinafter, andpointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of my improvedmachine for folding newspapers. Fig. 2 is a side View of the same, partsbeing broken out. Fig. 3 is an enlarged cross-sectional view of thetable and Fig. 4 is an enlarged cross-sectional view through the flutedrollers. Fig. 5 is a detail view of the cam. Fig. 6 is a detail view ofthe cam for operating the paper-holders. Fig. 7 is a cross-sectionalview of one of the rollers, showing the contiguration of the end disks.Fig. 8 is an enlarged detached sectional view on the line 3 y, Fig. 1,illustrating merely the mechanism for operating the pins T T. Fig. 9 isa detached view of the fluted rollers, in reduced size, showing theircrimping-teeth internieshing and the paper being folded between them.

Similar letters of reference indicate corre sponding parts.

The drivingshaft A is provided with the pulleys A. A flier, B, is hingedat B to the left-hand edge of a platform, 13, at the righthand end ofwhich platform an angle or other bar, B, is fastened edgewise, as shownin Fig. 3. To the under side of the flier B a curved arm, G, is fastenedat the hinged end, and to said arma wire, 0, is fastened, which isconnected by a spring, 0*, with the opposite part of the frame of themachine. \Vhen the flier is swung off the platform B", its free edgerests upon the frame D, on which a flat bar or plate, D, is mounted toslide diagonally, said plate D having diagonal slots D through whichpins D pass into the frame D. The frame D is provided with an edge, D,on which the swinging edge of the flier can rest, and anupwardly-projecting flange, D*. A hook, D projects from the end of thesliding bar or plate D and is adapted to engage with the pin Aprojecting from the side of one of the pulleys A. An anglebar, a, isfixed on the frame adjacent to and parallel with the inner edge of theflier B, Fig. 1. A spring, E is fastened to the frame of the machine andto a diagonal bar, E, fastened to the sliding bar D and an arm, D, ofthe same, which arm extends from the bar or plate D entirely across thefront of the machine and has its free end rested on the end of the barB, Fig. 1.

On the shaftAfive cylinder-sections, F, are mounted a short distancefrom each other, said cylinder-sections each being provided with as manyteeth F as there are to be folds in the paper.

Above the shaft A a shaft, H, is journaled in the frame of themachine,on' which as many sections G are mounted, which are shaped likethe sections F and have the teeth G, the sections G being shaped in sucha manner that the teeth of the same can be passed into the recessesbetween the teeth or projections of the sections F. The end sections, Fand G on the shafts A and H are provided with the teeth entirely aroundthe circumference, as shown in dotted lines in Fig. 7. The teeth F ofthe section F on the shaft A engage with the teeth of the section G2 onthe shaft H, so that said shaft H can be revolved from the shaft A.Through the spaces between the ends of the sections F the curvedguidebars I I, Fig. 4, are passed and fixed, between which the paperspass, the rear ends of the guide-bars being connected by the plates J,placed edgewise, between the inner edges of which plates a slot, J, isformed, the curved guide-pieces J forming the sides of the slot, saidguide-pieces be'ing fastened to the ends of the bars J.

On the outer surface of that section F next the pulley A, aplate, K,having two teeth, K, is fastened, which can engage with the two teeth Kof a collar, K on the shaft L, journaled below the flier at right anglesto the shaft A, on the end of which shaft the curved arm L is fastened,which can act on the under side of the flier, as shown in Fig. 3, theplates K and toothed collar being shown in Fig. 5.

A shaft, M, is passed through the several bottom sections, F, andmounted to revol ve on its axis, and is provided with spring-arms M,which can rest upon the sides F of the first teeth of the bottomsections, F, as shown in Fig. 2. An arm, M is fastened to one end ofsaid shaft and can be acted upon by a fixed segmental cam-plate, M,fixed to the frame of the machine, adjacent to the right-hand bottomsection, F, as shown in Fig. 1.

A pin, N, projects from the outer surface of the left-hand bottomsection, F, and can act on the tooth or projection N of a sliding bar,N, suitably guided on the frame, and having its end connected with thearm 0 of a vertical.

shaft, 0, having the two arms 0 and 0 Fig. 1, at right angles to eachother, in which a rod, P, is mounted to turn on its longitudinal axis,said rod being provided at one end with a cranked arm, 0, to which aspring, 0, is fastened, the other end of which is fastened to the arm 0on the shaft 0. The opposite end of the rod P is provided with a hook,P, and with a lug, P upon which two beveled projections, P and P, on theframe of the machine can act, in the manner that will be set forthhereinafter.

The shaft 0 is also provided with an arm, Q, connected with a slidingrod, Q, suitably guided, and having a projection, Q", on which a pin, Q,or projection on the left hand upper end section, G, can act. Acam-disk, R, is mounted on the shaft A and can act on one end of thelever B, pivoted at B3, and to that end of the lever B opposite the oneat the cam R a rod, S, is pivoted, which has the opposite end, S,forked, on which fork a crosspiece, S, is fastened, which slides on thetable T at the rear end of the machine, said crosspiece S being guidedby a pin, S passing through a longitudinal slot, S in the table T. A-short distance to the right of the cross-piece '8 two pins, T, projectup through apertures in the table, said pins being fixed on acrosspiece, U, on the end of a lever, U, pivoted be low the table T andprovided at the end opposite the pins T with a weight, U".

To the same end of the lever B to which the rod S is pivoteda rod, W, ispivoted, which is provided at its free end with a wedge shaped piece, W,adjacent to a fixed beveled projection, W, on the upper surface of thetable T, said wedge-shaped piece W being slightly to the right of thepivot of the lever U. The table T is provided with a slot, .W, as shownin Fig. 8. A spring, V, is fastened to that end of the lever B to whichthe rods W and S are pivoted and draws the same in a direction towardthe front end of said table T. Asuitable spring, M is provided forbringing the shaft M back into its original position after the arm M onthe same has been acted upon by the cam M, as shown in Fig. 4.

The operation is as follows: The sheet of paper is placed upon theplatform B and the flier B, as indicated by the heavy dotted line inFig. 3. against the prong of the hook D and draws the bar or plate Ddiagonally in the direction of the arrow on. Fig. 1, as said plate isguided by the pins D in the slots D", and thereby the sheet is shiftedor moved into the proper position, so that its edges rest upon the topsof the teeth F ofthe sections F, said sections being shown in Fig. 2.The pin A snaps off the hook D and then the plate D is drawn back in theinverse direction of the arrow :10 and into its original position by thespring E. At that moment the teeth K of the plate K on the end bottomsection, F, act on the teeth K of the collar K whereby the shaft L isrotated in the direction of the arrow 00*, Fig. 3, and the arm L isswung up and swings the flier B over upon the platform B whereby thesheet is doubledthat .is, folded at its middleand now rests upon theplatform B and upon the teeth F. By this time the sections F are in sucha position that the arm M passes under the segmental cam-piece M and isswung into the position shown The pin A of the pulley A strikes 7o indotted lines in Fig. 6, whereby the springarms M are swung down upon thesurfaces F of the teeth and hold the sheet on said surfaces. Thesections F and G continue to revolve and carry the sheet along with themand crease the same between the teeth F and G of the bottom and topsections, the paper passing between the guides I and I. When the teethof the sections begin to separate, as shown in Fig. 4, the creased paperrests against the plates J, as shown in Fig. 4, and the sectionscontinue their rotation, and at the proper ti me grasp a fresh doubledsheet from the platform B", and so on. As the sections continue torevolve, the pin N on the lower end section, F, strikes the projectionNfiwhereby the bar N is moved in the direction of the arrow as, Fig. 2,and the shaft-O is turned in the direction of the arrow at, Fig. 1, andthus the hookrod P is swung in the direction of the arrow m, Fig. 1, thehook passing over the top edges of the folded paper 1%, resting againstthe plates J. The lug 1 strikes the beveled projection P, and therebythe rod is turned ninety degrees and the hook end P is swung down, asshown in dotted lines in Fig. 4, and over the folded paper, the spring 0preventing the rod P from turning on its axis while it is being swungand before the lug P strikes said projection. By this time the pin Q onthe upper end section, G, strikes the projection Q on the rod Q',wherebythe shaft 0 is turned in the inverse direction of the arrow x and thehook P drawn through the slot J, and as it is in the position shown inFig. 4 it pulls the folded paper through with it, whereby the papers areagain folded-that is, the folded paper is creased at its middle by beingdrawn through the slot J. The rod P is swung in the inverse direction ofthe arrow 00 and when its lug P strikes the bevel pro- IIO jection P,the hook P is swung back into its original position and the paperdropped in the position shown in dotted lines in Fig. 1 and is betweenthe sliding cross-piece S and the pins T. By this time the cam R acts onthe rod R and swings the swinging end of the same, connected with thebar S, in the direction of the arrow 51;, Fig. 1, whereby the paper ispressed against the pins T by the cross-piece S. When the bar S is moveda short distance,

the wedge-piece W on the bar \V strikes the bevel V on the top of thetable T, whereby the said wedge-shaped piece is forced downward and actson the lever U and swings the same downward, whereby the pins T arelowered below the surface of the table T, permitting the cross-piece Sto press the paper beyond the pins T. The bars Sand \Vare then movedback by the spring V, and the pins T are raised by the weight U on theend of the le ver U, whereby the table is again ready for the nextpaper. The paper is thus first folded by the flier, so as to have aboutonehalf of its area. It is then grasped by the spring-fingers M and heldon the teeth surfaces F of the bottom sections and creased, the creasesmade by the sections F and G being at right angles to the crease made bythe flier. Then the folded or creased paper is again folded and creasedby being drawn through the slot J, the crease formed by being drawnthrough said slot being at right angles to the creases formed by thesections F and G and parallel with the crease formed by the flier.
